Pigment Information

This color contains the following pigments:

PBk7-Lamp Black

PG23-Green Earth


Pigment Name

PBk7-Lamp Black

Pigment Type

inorganic

Chemical Name

carbon

Chemical Formula

C

Properties

Lamp black is a very opaque, heavily staining black pigment that does not have much covering or tinting power. It is typically the most opaque black in watercolor form. Though a very pure black, it tends to muddy slightly in mixtures. Natural sources may be brownish or bluish in tone because of impurities. When used in oil paints, it is one of the slowest drying pigments, and should not be used in underpainting or applied in layers underneath other colors.

Permanence

Lamp Black is very lightfast and absolutely permanent. It is used in all techniques in permanent painting.

Toxicity

Carbon itself is not considered hazardous, however other combustion products that are hazardous are often present as impurities when Lamp Black is produced from natural materials. For this reason, commercial preparations of the pigment should be considere

History

Lamp Black is a carbon based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It has been used as a pigment since prehistoric times. It is the black found in Egyptian murals and tomb decorations and was the most popular black for fresco painting until the development of Mars Black.


Pigment Name

PG23-Green Earth

Pigment Type

earth

Chemical Name

hydrated iron, magnesium, aluminum and potassium silicates

Chemical Formula

K[(Al,FeIII),(FeII,Mg)](AlSi3,Si4)O10(OH)2

Properties

Green earth is a natural pigment that varies from yellow and olive to blue-green in its composition and hues. It is semi-transparent, has low hiding power and tinting strength, muddies and darkens in oil, and is particularly good for tempera and fresco painting.

Permanence

Green Earth has excellent permanence and lightfastness, although some varieties can be developed by light calcining. It is one of the most permanent pigments because Earths are not affected by sunlight or atmospheric conditions.

Toxicity

Green Earth has no significant hazards.

History

Terre verte is French for green earth. It was discovered in antiquity, and its use has been traced to the Ajanta caves in India and a variety of Roman sites, including Pompeii. Green Earth was very popular for underpainting flesh tones in medieval paintings because this green was the compliment to pink on the medieval color wheel. Its use declined after the Renaissance. The natural supplies of the pigment are mostly depleted, and manufacturers currently duplicate the hue using mineral bases like Viridian, iron oxide, or chromium oxide, or artificial ceramic colorants. Pigments sold under this name can also be the result of mixing Sienna and Phthalo Green.
